Hi all, I'm using VNC/noVNC for accessing the servers console in case of emergency. The console works fine, but I have got repeadly warning on the screen, that the wss://<host>:6100 could bot be connected with 3 recommendations - process is running /the console works/ - I'm able to connect the 6100 port by teknet form my pc - the certificate is imported In the /var/log/messages on HE I have found repeating message when the dialog appears. Jan 23 12:33:32 dipovirt-engine02 ovirt-websocket-proxy.py: ovirt-websocket-proxy[356] INFO msg:871 handler exception: Incorrect padding Nothing more is logged. The popus is quite annoing, since it appears every few seconds. my side: Mac OS X 10.13.2 FireFox 57.0.4 tested also on Ubuntu and Firefox 57.0.4 and works good,no exception. Any help or advise to figure what's wrong? regards Peter -- *Peter Hudec* Infraštruktúrny architekt phudec@cnc.sk <mailto:phudec@cnc.sk> *CNC, a.s.* Borská 6, 841 04 Bratislava Recepcia: +421 2 35 000 100 Mobil:+421 905 997 203 *www.cnc.sk* <http:///www.cnc.sk>
